Description

Technical Field

[0001] This invention relates to the field of gantry machining center technology, and more specifically to a five-axis gantry machining center. Background Technology

[0002] With the rapid development of modern manufacturing, five-axis gantry machining centers are playing an increasingly important role in the field of precision parts machining. However, existing five-axis gantry machining centers still face many technical challenges in practical applications that urgently need to be addressed.

[0003] Existing five-axis gantry machining centers often require manual intervention or multiple re-clampings during workpiece positioning and machining angle adjustments, resulting in inflexible machining position adjustments. Traditional equipment's positioning systems lack automated position adjustment capabilities, failing to quickly adjust machining position and angle according to the processing requirements of different workpieces. This leads to low processing efficiency, especially when handling complex, irregularly shaped workpieces, necessitating frequent machine stops to adjust equipment parameters, severely impacting production continuity and machining accuracy. Furthermore, the existing equipment's rotary arm system design is inadequate, failing to achieve precise multi-angle positioning, thus limiting the equipment's processing capabilities and applicability.

[0004] Post-processing cleaning is another crucial issue affecting equipment efficiency. Existing five-axis gantry machining centers generate significant amounts of metal shavings, cutting fluid, and cooling water during machining. These wastes and liquids accumulate in the machining area. Traditional cleaning methods rely primarily on manual sweeping, which is not only inefficient but also incomplete. Particularly concerning are the cleaning of the positioning base and worktable. Due to their complex structure, manual cleaning struggles to reach all corners, and residual shavings and liquids can affect the accuracy of subsequent machining operations and shorten the equipment's lifespan.

[0005] The existing equipment's cleaning system design has significant flaws, lacking effective debris collection and liquid discharge mechanisms. Traditional cleaning methods cannot achieve automatic debris collection and separation, and the poorly designed liquid discharge system is prone to secondary pollution. During the cleaning process, the equipment cannot achieve automated cleaning path planning, and the movement and turning mechanisms of the cleaning components are not flexible enough, resulting in numerous cleaning blind spots and unsatisfactory cleaning effects.

[0006] Furthermore, existing equipment has shortcomings in the design of its cleaning components. The cleaning brushes and water-pushing devices are not well coordinated, making it impossible to achieve efficient cleaning operations. Especially when dealing with complex contaminants mixed with debris and liquids, existing cleaning systems often fall short, requiring multiple cleaning cycles to achieve the desired results. This significantly increases equipment downtime and maintenance costs, impacting overall production efficiency. Summary of the Invention

[0018] The technical effects and advantages of this invention are as follows: 1. In the operation of this invention, the workpiece or object to be processed is placed on the top of the positioning base body and then placed in the center of the positioning frame. The transmission motor drives the first guide shaft and the first tooth to rotate. The meshing of the first tooth and the second tooth drives the transmission belt to rotate. The meshing of the third tooth and the fifth tooth drives the sliding positioning component to move under the guidance of the guide rail body. The threaded rod works on the guide positioning groove to position the guide slider, causing the guide slider to move left and right. The lifting column can be raised and lowered to adjust the angle. The first motor and the second motor drive the first rotating arm and the second rotating arm to rotate, thereby adjusting the processing angle of the processing part. This allows the equipment to adjust the processing position according to the actual processing needs, facilitating the processing of the workpiece or object. 2. After processing, a large amount of debris and water stains will fall onto the inner side of the positioning frame. The cleaning component is then installed on the square positioning block. At this point, the transmission belt rotates, causing the sliding positioning component to move to the back of the guide rail assembly. The transmission belt then stops rotating, and a hydraulic cylinder extracts liquid from the telescopic groove and injects it into the storage tank. Under pressure, the limiting plate, telescopic block, and fifth tooth rise, causing the fifth tooth to separate from the third tooth. The transmission belt then rotates, causing the cleaning component to rotate along with the first positioning guide rod and guide. The second and fourth teeth mesh, driving the cleaning positioning component to move. The cleaning brush... When the device is located at the bottom, it cleans the debris inside the positioning frame as it moves back and forth. The debris is swept to the back side, and then, guided by the two sides of the first positioning guide rod, the cleaning component rotates 180 degrees. When the cleaning positioning component moves to the top of the first positioning guide rod, the water pusher is located at the bottom. The water pusher then fits against the top of the positioning base body. As the cleaning component moves to the front, it pushes the water source to the front and guides the water source through the guide channel to the inside of the guide positioning channel. The water source is then discharged through the guide. After the operator collects the debris pushed to the back side, the cleaning work of the equipment after processing is completed, which facilitates the cleaning work. 3. When the cleaning component moves to the front and rotates for adjustment, the cleaning component rotates with the cleaning positioning component, causing the water pusher to move closer to the squeezing slope and squeeze out the water source absorbed by the water suction part at the bottom of the water pusher. Then, with continuous rotation, the water source inside the positioning frame can be cleaned, saving the operator's time for cleaning the equipment. 4. When the U-shaped sliding block moves to the turning part on the front and back of the first positioning guide rod, the U-shaped sliding block at the front end of the movement will first enter the turning part. At this time, the fourth tooth at the top of the first sliding positioning block in the turning part will separate from the second tooth. Then, under the push of the first sliding positioning block on the back, it will continue to rotate. After it contacts and engages with the second tooth at the bottom, the U-shaped sliding block on the back will be moved by the connecting rubber to complete the turning work, which is convenient for the operator to perform cleaning work.

At this time, the transmission belt 2023 rotates, driving the sliding positioning component 204 to move to the back of the guide rail component 201. Then, the transmission belt 2023 stops rotating, and the hydraulic cylinder 2046 works to extract the liquid inside the telescopic square groove 2042 and inject it into the storage tank 2047. Under the action of pressure, the limiting plate 2043, the telescopic block 2044, and the fifth tooth 2045 rise, causing the fifth tooth 2045 and the third tooth 2026 to separate. Then, the transmission belt 2023 rotates, driving the cleaning component 4 to rotate with the guidance of the first positioning guide rods 2018 and 2010, and then the second tooth 2025 and the fourth tooth 2035 mesh. The transmission drives the cleaning positioning component 203 to move. When the cleaning brush 403 is at the bottom, it sweeps the debris inside the positioning frame 102 as it moves back and forth. The debris is swept to the back side. Then, under the guidance of both sides of the first positioning guide rod 2018, the cleaning component 4 rotates 180 degrees. When the cleaning positioning component 203 moves to the top of the first positioning guide rod 2018, the water pusher 404 is at the bottom. The water pusher 404 is then attached to the top of the positioning base body 101. As the cleaning component 4 moves to the front, the water source is pushed to the front. The water source is then guided through the guide groove 103 to the inside of the guide positioning groove 105. The water source is then discharged through the guide. After the operator collects the debris pushed to the back side, the cleaning work of the equipment after processing is completed, which is convenient for cleaning. When the cleaning component 4 moves to the front and rotates to adjust the rotation, the cleaning component 4 rotates with the cleaning positioning component 203, causing the water pusher 404 to move closer to the squeezing inclined surface 104 and squeeze out the water source sucked by the water suction part at the bottom of the water pusher 404. Then, with continuous rotation, the water source inside the positioning box 102 can be cleaned, saving the operator time to clean the equipment. When the U-shaped sliding block 2031 moves to the turning part on the front and back of the first positioning guide rod 2018, the U-shaped sliding block 2031 at the front end of the movement will enter the turning part first. At this time, the fourth tooth 2035 at the top of the first sliding positioning block 2033 in the turning part will separate from the second tooth 2025. Then, under the push of the first sliding positioning block 2033 on the back, it will continue to rotate. After the 233 contacts and engages with the second tooth 2025 at the bottom, the U-shaped sliding block 2031 on the back will be pulled by the connecting rubber 2034 to complete the turning work, which is convenient for the operator to carry out cleaning work. During the processing of the workpiece, a shelf can be placed on the top of the telescopic positioning sleeve (2037) and the square positioning block (2039) so that the operator can place the tools that are readily available on the shelf. This makes it convenient for the operator to pick up the workpiece when checking the processing status. During processing, the telescopic rod (2038) is pushed to both sides to retract into the telescopic positioning sleeve (2037), and then the cleaning component (4) can be removed to avoid impacting the workpiece during processing. This also makes it convenient for the operator to install and disassemble.
